The do-create-resource action is enhanced to use REST API with the Identity Manager 4.8 version. However, if you are on versions prior to Identity Manager 4.8.2, this can only be achieved by manually editing the XML file.
The following procedure provides instructions on modifying this setting manually through the XML file:
Log in to Designer.
Open a policy in the policy editor.
Select the create resource action in the Do field.
Click the XML Source tab.
To use REST API, set the value of the use-rest parameter to true in the XML file. To use SOAP API, set the value to false. By default, the value is set to false.
This capability is available through the Designer policy builder from the Identity Manager 4.8.2 onwards. For more information, see Create Resource action in the NetIQ Identity Manager - Using Designer to Create Policies.
